SPECIFICATION forming part of Letters Patent No. 450,006, dated April 7, 1891.

Application filed January 9, 1891. Serial No. 3'77,2'7S- (No model.)

To all whom it may concern:

Be it known that we, FRANK. G. DODGE, of \Viscoy, in the county of Allegany, and DAN- IEL O. STARKS, of \Varsaw, in the county of Vyoming, and State of New York; have invented a certain new and useful Improvement in Land-Rollers; and we do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the drawings accompanying this specification.

Our improvement relates tothat class in which the roller is made in two sections, one standing in advance of the other, the two making the length of an ordinary roller.

The invention consists in the jointed connection between the sections, and also in certain devices by which the rollers may be locked to follow in direct line, as hereinafter described and claimed.

In the drawings, Figure 1 is a plan view of the machine. Fig. 2 is a side elevation. Fig. 3 is an enlarged plan view of the connecting devices between the rollers. Fig. 4 is a vertical section of the same. 7

AA indicate the two short rollers, standing one in advance of the other and out of line, as in other rollers of the class. The inner ends lap past each other, so as to leave no break in the surface over which they pass.

B B are frames to the rollers, extending over the tops of thesame longitudinally, consisting of standards a a, in which the journals of, the rollers turn, and shallow boxes I) b, which serve to receive any material forming weight, by which the rollers are loaded down whenever desired.

These rollers are connected by the following means:

D D is a double-armed bearing attached rigidly to frame B of the rear roller and projecting forward a suitable distance, where it is formed with a circular disk 0.

E is a circle-plate resting on top of diskc, being attached by a bolt (Z, around which it turns freely.

G is an arm connected with the front frame B by means of cars ff of the frame,in which turns a spindle g, that forms the front end of arm G. This forms a joint at right angles to the length of the rollers, which joint allows both of said rollers to tilt up and down at either end in passing overirregularsurfaces. The opposite end h of arm G passes between lugs i i: of the circle-pla e E, and projects over a segment 75 on the fixed bearing D D. At the ends of this segment are pins or lugs Z Z, which form stops to the swinging of arm G in either direction beyond a certain limit.

By the construction above described a universal joint is produced, first, vertically by means of the spindle g, resting in the bearings ff, which allows the ends of the rollers to rise and fall, and, second, horizontally by means of the circle-plate E turning on the disk 0, which allows the rollers to turn out of linein passing corners and curves, as indicated by the dotted lines, Fig.1. It is an objection to ordinary rollers of the kind that in thus turning corners and curves there is no stop to limit the cramping action, and sometimes the turn is so sharp that the rollers will cramp to a right angle, or even more, and frequently disarrange the machine. In thisinvention the difficulty is obviated by the stops Z l, which limit the swing of the arm G and stiffen the connection when the parts meet. By this means the rollers cannot cramp beyond a certain angle, which is such as to cause the rear roller to properly follow the front one in passing a corner. In some cases, and especially with heavy rollers, a segment 7t is used in front of the circle-plate E, attached to projections 00 a: of the bearing D D, said segment being also provided with stops 1 l, similar to those on the rear segment, and for the same purpose.

In straight work it is designed that the rollers shall stand square and run in a direct line. To insure this the following arrangement is used:

m is a notch formed centrally in the inner edge of the rear segment 70.

n is a slide on arm G, pressed back by a spring 0 toward the segment. This slide has a shank p, which passes through a slot 4" of arm G, and has a detent s, that engages with the notch m. \Vhen the parts are so engaged the arm G is locked to the segment 7t, and both rollers stand square and move in a direct line.

6 is a rod connected by a suitable joint with the top of slide at, thence extended forwardand jointed to a crank it of a shaft '0, extending longitudinally of the frame B, resting in suitable bearings, and having at the opposite end a foot-lever m, which is turned at any time by the driver, who presses his foot on it. By so pressing on the treadle the shaft is turned, and the connecting-rod drawn back, the detentfreed from the notchinthe segment, and in that condition the. rollers are free and can be cramped in turning corners.

J is a spring of any suitable kind, having a knucklej, fastened to arm G by a set-screw, said spring extending transversely and bearing on a pin 6 of the frame B of the front roller. Said spring tends to hold the roller down and prevent it from tilting when it stands at an incline.

Having described our invention, what we claim as new, and desired to secure by Letters Patent, is-

1. In a land-roller, the combination of the double-armed bearing D D, rigidly attached to the frame of the rear roller, the arm G, jointed to the frame of the front roller, the circle-plateE,attached to said arm and jointed to the bearing 1) D, and the segment is, attached to the bearing D D and provided with pins or lugs ZZ at its ends, which serve as stops to the side motion of bar G, as herein shown and described.

2. In a land-roller, the combination of the double-armed bearing D D, rigidly attached to the frame of the rear roller, the arm G, jointed to the frame of the front roller, the circle-plate E, attached to said arm and jointed to the bearing D D, the rear segment 7c, attached to the bearingD D and provided with pins or lugs Z Z at its ends, and the front segment 7c, similarly attached to front pro ections 00 0c of the bearing and provided with pins or lugs Z Z at its ends, as shown and described, and for the purpose specified.

3. In a land-roller, the combination of the double-armed bearing D D, attached to the frame of the rear roller, the arm G, jointed to the frame of the front roller, the circle-plate E, attached to the arm and jointed to the bearing, the segment It, provided with the notch m, the slide 72, provided with the detent 8, engaging said notch, the spring 0,bear1ng against the slide, the shaft 4;, provided with treadle 10, attached to the frame of the front roller, and the rod 15, connecting the slide at with a crank it of shaft 4), as shown and described, and for the purpose specified.

4. In a land-roller, the combination of the double-armed bearing D '1), attached to the rear roller-frame, the arm G, jointed to the front roller-frame, the circle-plate E, attached to arm G and jointed to the bearing D D, and the spring J, attached to arm G and bearing on a pin 6 to prevent tilting of the front roller, as herein shown and described.

In witness whereof We have hereunto signed our names in the presence of two subscribing witnesses.
